GOBPORKTIONT OLE NEW JERSEY GALKING: MACHINE This invention relatesto calking machines and more particularly to a support for a calking machine adapted for use in calking a seam between a nozzle or the like, and the sheet of metal to which, the nozzle is secured. The invention will be better understood from the following description and the-accompanying drawings, in which I have shown a selected embodiment of the invention, andin which Fig. 1 is a partial longitudinali section through a drum showing one use to-which the invention may be put.

Fig. 2 is a view on alarger scale, showing the device appearing in Fig; 1'.

Fig. 3 is a View taken on the line 3'-3of Fig. 2.

Fig. 4: is a view taken on the line H of Fig. 2.

Fig. 5 is a view taken on the line 55.0t Fig. 2.

For the purposes of, illustration, I have shown my invention as employed to calk a seam between asheet in the form of a drum and a nozzle secured'to the drum. The drum sheet is indicated at 1 and, as shown, hasan opening, the edge of which is designated2. Secured to the drumiadjacent the opening is a nozzle outlet 3, the securing means being omitted from the drawings. Such means may comprise welding, riveting, or any of the well-known forms of attachment.

Disposed in the nozzle 3 is a bushing comprising a hub L and a plurality of arms 5 extending outwardly therefrom. This bush ing, and more particularly the arms, are of such size as to fit the particular nozzle with which the device is being used. The bushing may be retained in position in the nozzle by any suitable means such as a plate 6 secured to the nozzle as by bolts 7.

As plainly shown in the drawings, the hub i has a central bore 8 within which is received a post 9, the form of which is best seen in It will be noticed that the post has two substantially parallel portions offset with respect to one another, and the upper portion is adapted to support a calking tool substantially over the lower portion, so that the tool will be disposed substantially at the center 1928. Serial No. 291,998.-

of' the nozzlez. The-reason for this construction will be-made-apparent later.

Slidably mountecb on theupper end of the post is a collar 1-0 which may be secured in any desired position on the post by'means of a' set screw 11. The collarhasatransversely extending"memberlQat the end ofwhich is a face plate I 13'having a. recess l t-within which is slidablymounteda bracket 15: This bracket has adownwardly extending arm l 6=having an enlargedouter end 17"which is boredto receive the hammer 18'. The bracket may he slid back and forth on theface plate 13, and may be secured in adjustable position as by means of the slot-ted connection best shown inFig. 2, and which comprises a slot 19 which receives a bolt 20 which isthreaded into'the collar.

The upper end of the'hammer has secured thereto the cap 21 which isprovided with studs 23 passing through transversely extending-lugs 24 on the bracket arm'16. Between the lower heads of the studs and the lugs 24 are disposed springs 25"- to absorb thevibration'of the hammer. The details of the hammer have not been shown because any suitable-- type of" hammer may be used. The hammer'is shown as being of the wellknowntype operated by air which is supplied througha hose'26, the passage of air T being contro-lled'by the-valve 27 The tool operated by the hammer is shown-at 28, and it will beseen' that by the above construction, this tool is supported-on a post which is disposed substantially at the center of the opening surrounded by the seam which it is desired to calk, this seam beingthe one between the edge 2 and the nozzle.

Th-e'bushing may be secured in'thenozzle by any suitablemeans such asthe set screw 29; which is turned outwardly till its head engages the wall of'thenozzle'. Then,-as the hammer is operated to calk' the seam, the

post Q m'aybe rotatedin thebore 8. Preferably', the sheet-is disposed horizontally, and

it will be'noticed that the-bottorn 29 of't-h'e post'9 does not touch the plate 6, andtherefore the entire weight of the assembly is transmitted throughthe tool 28 to the seam. This weight gives thenecessary reaction to the hammer blows to properly calk the seam. The tool is also substantially over the center of the opening, so that upon rotation of the post the tool will always be in proper position with respect to the seam.

I claim 1. In a ealking device for use with a sheet having an opening therein with a seam adjacent said opening, a support rotatably carried by said sheet and disposed substantially at the center of said opening, and a calking tool on said support and adapted to calk said seam.

2. In a calking device for use with a sheet having a nozzle secured thereto and adjacent an opening therein, a post supported in said nozzle and extending through said opening, and a calking tool supported on said post and adapted to calk the seam between said nozzle and said sheet.

3. In a calking device for use with a sheet having a nozzle secured thereto and adjacent an opening therein, a post supported in said nozzle and extending through said opening, a calking tool supported on said post and adapted to call; the seam between said nozzle and said sheet, and means for adjusting said tool lengthwise and laterally of said post.

4. In a calking device for use with a sheet having an opening therein and a nozzle secured to said sheet and substantially concentric with said opening, a bushing disposed in said nozzle and having a bore substantially at the center of said nozzle and opening, a post rotatably mounted in said bore and having an offset portion extending through said opening, and a calking tool supported on said ofiset portion and adapted to calk a seam between the sheet and the nozzle.

5. In a calking device for use with a sheet having an opening therein and a nozzle disposed substantially concentric with said opening and secured to the sheet, a post having parallel portions ofiset with respect to each other, means for securing one of said offset portions substantially at the center of said nozzle and in a position wherein the other offset portion will extend on the other side of said sheet from said nozzle, and a calking tool supported on said second offset portion on the same side thereof as said first ofi'set portion.

6. In a calking device for use with a sheet having an opening therein and a nozzle disposed substantially concentric with said opening and secured to the sheet, a post having parallel portions offset with respect to each other, means for securing one of said offset portions substantially at the center of said nozzle and in a position wherein the other offset portion will extend on the other side of said sheet from said nozzle, and a calking tool supported on said second offset portion and adapted to calk a seam between the sheet and the nozzle.

7. In a calking device for use with a sheet having an opening therein and a nozzle disposed substantially concentric with said opening and secured to the sheet, a post having parallel portions offset with respect to each other, means for securing one of said offset portions substantially at the center of said nozzle and in a position wherein the other offset portion will extend on the other side of said sheet from said nozzle, a ealking tool supported on said second offset portion and adapted to calk a seam between the sheet and the nozzle, and means to adjust said tool lengthwise and laterally of said post.

8. In combination, a post, a collar slidably mounted on said post and having a face plate thereon, a bracket slidably mounted on said face plate and having an arm provided with a bore, a calking tool slidably mounted in said here, and a spring acting between said bracket and said tool to absorb vibrations in the tool.

9. In a calking device for use with a horizontally disposed sheet having an opening therein and a nozzle secured to said sheet and registering with said opening, a bushing disposed in said nozzle and having a central bore, a post disposed in said bushing, and a calking tool supported by said post and adapted to calk a seam between the sheet and the nozzle, the bottom of the post in said here being unsupported whereby the weight or" the tool and the post will be transmitted through the tool to the seam which is being calked.

10. In a calking device for use with a drum having an opening therein with a seam adjacent said opening, a support rotatably carried by said drum and disposed substantially at the center of said opening, and a calking machine on said support and adapted to calk said seam.
